Wi-Fi calling not working after upgrading to iOS 17.0.1
After I upgraded to the latest operating system, I have lost the ability to make Wi-Fi calls. Bluetooth is enabled and I have tried in airplane mode and gsm mode (although my plan does not work in Africa), both to no avail. FaceTime works fine for communicating with family and friends, but I cannot call non Apple numbers (businesses, etc.).
